[QUOTE="JEVapa, post: 3992579, member: 41176"] I use a vice block but I've moved to an action rod. The vice block is still good for torquing the barrel nut but not so much for anything else IMO. You still need to lock the barrel (in a barrel vice or action rod) for torqued MD especially for suppressor use. I use barrel nut shims only for timing a pesky barrel nut. Never for headspace - per what [USER=17621]@SPDguns[/USER] says. Don't stick the shim in between the receiver face and the barrel extension, just between the extension (flange) and the nut. I know some guys that use shim material around the barrel extension to "bed" the barrel, makes sense I guess but I don't think it helps enough to mess with it, unless your barrel just rattles around in the receiver. This is for timing your barrel nut that has holes and/or notches in it for your gas tube. If you have a non-timed barrel nut like a DD or midwest industries that is round and sits under the gas tube and has a clamp for a free float tube then --> 34ft lb. Some places say 35, some 40, some 60, but just refer to a 23&P. Get a 23&P...must have. NO RED THREADLOCKER EVER ANYWHERE ON AN AR 👇👇 [URL unfurl="true"]http://www.combatsimulations.com/ar15/manuals/tm%209-1005-319-23%26p.pdf[/URL] [/QUOTE]
